At the end of the British Rule and during the time it was called Rhodesia, this area was a food exporter with very productive farms and ranches. The odds say that there has to be at least some successful native farmers now but Mugabe will destroy them along with the rest of the country as he sells it to the Chinese. Failing Despots reach out to their peers and China has the money.
A lot of the Rhodesian farmers relocated to Zambia and Mozambique where they were actively recruited by the national government to produce badly needed food the locals just weren’t up to growing. The farmers put conditions on their relocation, however, only short-term leases on the land, no ownership and a quick escape route in case things turn sour. Mugabe has done very well in all this, he is a major league thief who has squirreled billions abroad, a typical “communist” first among equals with an emphasis on the “first”.
